BAKlNG-OVEN.

SPECIFICATION forming part of Letters Patent No. 643,202, dated February 13, 1900. Application tiled February 28, 1899. Serial No. '706,4'77I (No model.)

To (LZZ whom, t may coaccrn:

Be it known that LICHARLns RINCK, aciti- Zen ot the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Baking-Ovens, of which the following is a specication.

My invention relates to improvements in baking-ovens. One of its objects is to provide improved means for feeding small objects directly through from one end of the oven to the other, with means for adjusting the guide-rails and closing the openings at the ends of the oven.

It also consists in certain details of construction and combination, all of which will be more fully set forth in the description of the accompanying drawings, in which- Figure l is an end elevation of my improved oven. Fig. 2 is a vertical section on linerr, Fig. l. Fig. 3 is a perspectiveview of a section of the guide-rails. Fig. 4 is a perspective view of one of the baking-trays.

A represents the brickwork of the oven.

B2 represents the oven or baking-compartment.

C represents the fire-box, and D the ash-pit.

l, 4, and 5 represent the longitudinal ues, and E the chimneys.

The lower oven-compartment B'/a is open at both ends, preferably the whole width of the compartment. has its top and bottom walls inclined from one opening to the other. I represents guiderails traversing said oven-compartment and projecting a short distance at either end. These rails rest at the ends of the oven upon vertically-adjustable cross-bars J.

j represents adj usting-screws tapping the lugs K, projecting from the plates 7o, and.

adapted when turned to raise or lower the cross -bars J. The cross bars J also carry sheet-metal aprons L, which are raised and lowered with the cross-bars to close the lower portion of the oven-openings.-

M represents vertically-sliding doors to close the oven-openings above the rails I.

m represents counterweights to assist in raising the doors and to hold them in the raised or other adjusted position.

The guide-rails are preferably of special form to withstand the heat without warping This oven-compartment alsol and not to clog or bind from any material dropped uponthem from the pans or trays, and consist of the wide outside rails t', the inner narrow rails i', and the tie-rods t'which pass through sections of tubing 713 to hold the rails the proper distance apart.

The mode of operation is as follows: Are is kindled on the grate r, the products of combustion pass through the flue l, which is U- shaped, to the opposite or rear end of the oven and returned, thence through vertical flues in the extensions P to one limb of the U-shaped flue 4, which it traverses, and by vertical Hue H reaches the U-shaped flue 5, and thence to the chimney. The side walls are extended at P for the vertical lines, so that the openings at the ends of the oven-compartment may be the full width of the compartment. This form of oven is particularly adapted to bake crackers, pretzels, and similar small articles. The material to be baked is placed upon pans or trays similar to the tray R of Fig. 4, which may have a continuous or perforated bottom, depending upon the material to be baked. These pans or trays are fed 'at the upper end onto the inclined rails I, so as to rest between the outer rails t' and upon the rails t, the incline being such that the operator is enabled to push the preceding trays along down the incline by pressing upon the edge of the last tray, so as to intermittently feed the trays throughV the oven and out at the opposite end without buckling or superimposing one of the trays upon the other. The form of rails is such as to greatly assist in the easy sliding movement of the trays thereon and to guide them in regular order through the oven. The upper oven-compartment B has a door h' and may be employed for baking or as a drying-oven.

.The apron closes the lower portion of the oven-opening, while the doors M cover the upper portion and may be readily raised out of the way when desired. In practice the doors M are left slightly open to permit the trays to be fed beneath the lower edge of the doors. It will be apparent that the oven can be -built with a single oven-compartment, if desired. The adjustment of these rails in the oven-compartment is important, first, to lift the rails to varying heights above the 'oor of the oven, which varies with the character ot IOO material being baked, and also to regulate the angle ot' inclination of the rails to facilitate easy movement of the trays Without buckling, also dependent upon the character and Weight of material operated upon, in order that the trays may not buckle in being pushed through the oven.

Having described my invention, what I claim is- 1. In a bake-oven in combination with an oven-compartment open at both ends, rails adapted to guide and supporta series of bal;-

` ing-trays, consisting of the outer raised guiderails, the inner supporting-rails, tie-rods and means substantially as shown for holding the several rails the requisite distance apart, substantially as specified.

2. In a bake-oven and oven-compartment open at both ends, having inclined t-op and bottom Walls, inclined guide-rails traversing said oven-compartment, means substantially as shown for independently adjusting the height of the rails at their opposite ends, and trays adapted to slide along said rails,Where by the operator is enabled to change the angle of inclination of the rails and to push the several trays down the incline by pressing on the end tray substantially as specified.

3. In a bake-oven and oven-compartment open at both ends, heating-lines above and below said compartment, inclined rails traversing the oven-compartment, means substantially as specified for independently adjusting the opposite ends of the rails to elevate or change the angle of inclination thereof, and a series of trays adapted to be fed,

through said oven by pressing upon the end trays at the upper end of said inclined rails, substantially as specified.

4. In a bake-oven and oven-compartment open at bothends,inclined rails traversingsaid compartment,verticallyadjustable cross-bars supporting said rails, aprons secured and traveling With said cross-bars to close the lower portion of said oven-openings and counterweighted doors sliding in guides and adapted to close the upper portion of the oven-openings, substantially as specied.

5. In a bake-oven, an oven-compartment open at both ends and having its top and bottom Walls inclined, inclined rails traversing said compartment,verticallyadj ustable crossbars supporting` said rails, aprons secured to and traveling With said cross-bars to close the lower portion of said oven-openings, and counterweighted doors sliding in guides, and adapted to close the upper portion of the oven-openings, substantially as specied.

In testimony whereof I have hereunto set my hand.
